My Pekin/Campbell duck was acting listless yesterday, very unusual for her. I checked her all over, she looked fine. Then I found this this morning: **WARNING GRAPHIC** I cleaned it up really well, and tried to push it in very gently. It wouldn't go, so I stopped. It then started to bleed. She is in a quiet, dark place with lots of clean shavings to rest in. Is there anything I can do?
